msnwnsnme iu'rann'rus Application med September so, ;ez-1. serial m. 740,758;

The present invention relates to apparatus for cleansing or washing and more particularly for the washing of household dishes.

The object of the present invention is to provide an apparatus of this character which shall be of inexpensive cost and simple construction, easy of operation, and adapted for. attachment and use on a wide variety of water faucets., To the above end the present inventionconsists in the devices and combinations of devices hereinafter deseribe'd and more particularly defined in the c'laims.

ln the accompanying drawings which illustrate what is now considered the preferred form of the invention,`Figure 1.is a side' view, partly in elevation and partly in section, showing my improved apparatus attached to a faucet with the parts in position to deliver soapy water through the 0 spray nozzle; Fig. 2 is a Vertical view transversely of the faucet looking toward the right, partl in elev'ation and partly in section, of a portion of the apparatus showing the method of attachment to the faucet and the construction of the valve.

The improved washing appa'ratus is of the type which is adapted to be connected with the ordinary domestic hot water faucet and is provided with la hose and spray nozzle and with a soap cont-ainer, suitable controlling devices being provided whereby either soapy or clear hot water may be directed in a plurality of forcible small streams against the dishes, first to cleanse them with the soapy water and then to rinse them with the clear hot water. u p

'In the illustrated embodiment of the present invention the main portion or valve casing 5 is provided with 'a laterally extending ,40 portion 6 terminating in an enlargement or head? which is arrafi^ged to connect at its top with /the discharge end ofthe faucet 8, and at'its bottom with alhose, 9 having the anozzle 10.' The head' 7 is provided with a 2:45 short water passage 11 for permittng the flow of a stream of water direct-y from the faucet to the hose. i

` Integrally formed with the valve' casing 5'- at the bottom thereofv is the cap `or closure 56 13. which has a downwardly extending internally threaded lip to receive and' support the cylindrical soa container 14. 'Preferably the engaging t reads on' the container and lip' are of relatively `large size and few 1n number so that not only may the threads be easily engaged, but the container may be removed or replaced with a minimum of turnmg. To prevent the 'slipping of the hand of the operator inl removing orreplacing the container, the latter is provided at its bottom with theprojections 15. c

Provision is made for. diverting a portion of the Water from thefaucet month to the soap container and thence back to the stream adjacent the hose connection and this is accomplished by means of branch water passages in the casing 5, the later'ally extending portion 6, and the head 7. For example, the inlet branch passage 17 conducts the water T from the month of the faucet through the passage 18 in7 the valve 19 and 'thence downwardly through the pipe 20 into the soap container. i The soapy water is conducted from the top of the container throughxthe' outlet branch passage 21 to a point adjacent the hose. connection where it mingles with the main stream of lwater flowing directly through the passa-ge 11 from the faucet to the hose.

The branch passages /17 and 21 ar'e preferably formed of small -pipes or tubes around which 'the metal of the casing 5 and its lateral projecting portion 6.and head 7 is cast. The depending pipe 20, which extends downwardly into the container, is preferably threaded into a central opening or passage in the casing, a nut 23 on the threaded upper end of the Vertical pipe 20 serving to hold fixed in position against the boss 24 the perforated plate or screen 25, the margin of which in turn holds against its seat the washer 26 for preventing-leakage between' the container 15 and its closure 13.l

The common domestic hot water faucet is constructed with a smooth discharget end, that is, without the ezternal threads commonly present in kitchen cold water faucets. accordingly, a common method of attachment of such appljances has been to employ a rubber'hose, the end of `which is passed over the diseharge end of the faucet, or to secure to the-endof the faucet by screws or otherwise a threaded sleeve or collar to'receiv'e the ordinary hose coupling. With the present invention these objectionable methods'of con- 105 nection are av,oided and the appliance is held in direct engagement with the discha'rge end A of the faucet without the use of rubber hose ioo yoke,

or a special attachment seeured to` the end of the faucet.

This is accomplished in the accompanying embodiment of the present invention by forming in the head 7 of the extension 6 an annular'recess or seat 31 of suflicient radial width to accommodate the various diameters of faucets commonly found in domestic use. Centrally located within the recess or seat is the upwardly extending projection or tube 32, through which extends the main Water passage 11. Co-axially positioned within the main water passage 11 at its inlet end is the upwardly bent tube 33 which forms the inlet of the branch passage 17. A rubber washer 34 in-the recess or seat 31 is preferably provided to insure a tight joint between the end of the faucet and the seat.

The means shown in the drawing for,securing the appliance to the faucet com rise an abutmentfor engaging the under si e of the faucet at the rear thereof, and clamping devices intermediate this abutment and the head 7 which connects with the discharge end of the -faucet, these devices extending over the top of the faucet andzencircling the valve post of the faucet. The rear abutment 37 has its upper end 38 bifurcated or saddle shaped to fit the rounded under surface of the faucet and is adjustable to various heights by means of its screw threaded stem 39 fitting in the internally threaded hole in the abutment 41l on the valve casing 5. By rotating the abutment 37 this may be adjusted higher or lower so that the seat 31 will be brought into proper angular relation with the discharge end of the faucet 8.

The clamping devices for securing the a pliance to the faucet comprise two laterally extending ears or lugs 43 at the top of the casing 5, in which are pivoted the'threaded links or arms 44, a yoke 45 encircling the valve post of the faucet and resting upon the top of the faucet-v in the front and rear of the i ppst and having bifurcated lateral extensions 46 `to receive the links 44. Washers 47 and thumb nuts48 on the-threaded links 44 enable the casing to bedrawn up with the real' abutmentv 37 and the seat 31 in firm engagement with the faucet, holding the appliance' fixedly in position.

It will be observed that the applance is mount'ed directly beneath the faucet with the valve and soap container in substantial line with the faucet, where they will not inter'fere with the adjacentstructures or with the operator. The appliance may be easil and quickly remov'ed by merely loosening ne' or both of the Wing n`uts and swingliig the threaded links out pf engagement with the the yoke being formed of such size and shape that when disconnected from the links it may be easily removed from the faucet without disturbing any of the parts thereof.

In order to insure the proper circulation 'made up of 'of water through the soap container the disvthe branch passages and soap container.

The hose 9 is attached to the head 7 with the common hose connection comprising the internally threaded rotatable sleeve or connector 53 which engages the externally threaded cylindrical extension 54, the packing washer 55 being provided to prevent leakage.

In the operation of my appliance, after the same has been attached to the faucet as above described, the soap container is partially filled with pieces of soap and secured in place. The faucet being open and the valve 19 being turned to the position shown in Fig. 1, a stream of hot soapy water will be discharged from the nozz e 10, this stream beinzJ the main stream flowing throug 1 the pass'age 11 and the branch stream flowing through the soap container. The nozzle end of the hose will be manipulated by the operator to direct the hot soapy water over the dishes, and after these are cleansed, the valve 19 Will be turned to closed position, Whereupon the flow through the soap container will cease and a stream of clear hot water will be discharged from the nozzle to rinse the dishes. By varying the position of the-valve 19, more or less soap may be used as desired.

The provision of a short direct water pas- Sage-from the faucet to the hose is of advanta e, inasmuch as it avoids any throttling e ect and insures the discharge of water at the nozzle under substantially full head or pressure, thus enabling the apparatus to be successfully used where a relatively low faucet ressure obtains.

T e mounting of the apparatus 1n direct engagement with the discharge end of the faucet without rubber hose or special fitting simplifies the construction, facilitates the mounting, reduces the cost, and provides a practically Permanent structure which sufi'ers no depreciation or wear and which can be (pliickly removed by the hands alone, leaving t e faucet and adjacent structures free and clear of all parts or fittings. Furthermore, the present apparatus has no small parts which are liable to be lost or misplaced and is practically universal in its application to the various sizes and styles of kitchen hot water faucets now in common use.

While I have illustrated and described my improved apparatus as applied to a kitchen hot water faucet and as particularly adapted for the washing of dishes, it is not necessarily limited to such use but capable of other uses,

and in other locations, and with other mate: rials than soap, as 'Will be apparent to those skilled in the art. Where, therefore, in the* claims specific reference is made to a soap container this term is to be understood as including containers for other materials besides soap. i
